> 90% of our checkin users have moved over to Swarm and continue to check in

You/Foursquare really should clarify exactly what you mean by this - we keep hearing how "successful" Swarm is but it seems most [former] users (including me) and their friends (including mine) stopped using it when (or shortly after) the switch happened.

Right now Foursquare sounds like Google in the early days of Google+ where they were touting how much people were posting but everybody was saying they never saw any activity in their stream.
